Another object of theinvention-is the provision of a practical whistle which,'when not being operated, will be protected by a connected device from the entry of 'dirt,

particles oflint, or other foreign matter.

Another object of the invention is the'pro visions of a simple and inexpensive pro tected whistle capable of being operated practically as readily as an unprotected whistle. I

Other objects will be in part obvious and in part pointed out hereinafter. I

The invention accordinglyconsists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims;

larger than actual size, in order to more clearly show the parts. Whistles, horns, etc, not infrequently become inoperative or inefficiently operative by reason of the'clogging of the whistle pa sages by extraneous matter, and this is especially thecase where the whistle is small 7 and carried in the pocket. Tnfthe case of a police whistle, it is most desirable that it shall be ready :tor' eiiicient operation at all times, and the presentinvention has for an important object the protection. of a whistle which will fulfil the requirements oi a police I -whistle and be ready for operation on the instant. v a p Referring now more specifically to the drawings wherein the invention is illustrated as embodied 111 the type of whistle generally employed by the police, the numeral 1 indicates the body of a whistle coma prising a cylindrical chamber having alongitudinally extendingpartition 2 dividing the chamber into two compartments which preferably are of different volume, the partition 2 being set somewhat oil? the central axial line. The numeral 3 indicates acircular plate extending transversely of the body 01" the, whistle and fixed to the partition 2, the edges of this plate being spaced from the wall of the body adjacent the vents or vent openings 4 in said body so that the air may pass around the edge of the plate 3 3 in the body and out of the vents l.

entryoi dirt, particles 01 lint, or other for i In order to protect the whistle from the the whistle or its passageways would inter,

; fere with its efficient signaling operation and Fig. 2 is. a longitudinal section o1 the whistle shown in Fig. 1, and with the whistle even render it soundless, means are provided ioropening and closing the openings in the whistlethrough which such foreign matter might enter. in the present embodi ment there are two openings or vents i and a third opening, or mouth 5, through which latter ELHTBHtGIS the whistle in normal op eration. The means employedeior preventing the entry of foreign matter may be characterized as valves inasmuch as such means has a function of opening and closing ports, such as the vent and mouth referred to. In

5 the present embodiment vent protecting and mouth protecting valves are employed, the ventprotecting valves being embodied in a sleeve 6, movable longitudinally back and forth on the body of the whistle so as to open and close the vents 4. Also in the present embodiment the mouthpiece of the whistle is one with the sleeve 6 and is therefore movable longitudinally relative to the ,whistle body with the sleeve 6, and the an extension, viz..the sleeve 6, which extension not only forms the valves for the vents 7 but also associates the mouthpiece and these V fective manner.

- "In the present embodimentthe. valvefor the mouth 5 comprises a shoulderedcylindrical valve 8, having a fiat upper end, this valve being adapted to'nicely and'easily fit the mouth or opening 5 in the outer end of V the mouthpiece so as to close the same against the entry of foreignmatter. In'thejmodification illustrated in Figs. 1, 2 and 8, the

valve Sis supported within the whistle by a stem 9, the stem in the present embodiment comprising a flatrmetallic plate fixedto a ring9, the latter being fixed'to the inner wall of the body 1, the stem Qlying in about the same plane as the partition 2. As shown, the valve 8 is stationary relative to the body 1, and, as will hereinafter appear,

the valve 8 will "be disposed" within the ready to be operated. a

In operating the form illustrated inFigs. 1, 2 and 3, the mouthpiece portion is moved relative to the body portion until the sleeve.

mouthpiece in the vent closing direction may .be'limited by the provision of a slot 10 in'the body 1 engaged by pin 11 carried by the sleeve 6. Or the'shoulder in the stationary valve 8 may be so positioned as to cooperate .withjthe' inner face of a flange 12. ofthe mouthpieceto limit the valve closing movement. l/Vl1en theopenings in the whistle are thus closed,*the interior of the device is practically sealed against the entry of foreign matter, as referred to, and it may be kept 1n 1 the pocket withoutfear of its efiiciency being impaired b -thelodgment of extraneous matvalves embodied in the latter. this wise the mouthpiece may be considered as having valves with the body in a practical and cf mouthpiece when the mouth 5 is open and ter within the same. When it is to be used, the mouthpiece may be drawn outwardly relative to the body 1, thus uncovering the vents 4 and the mouth 5, and-placing the instrument in condition to be sounded in the customary manner; By providingthe mouthpiece with some means for engaging the teeth of the person using theinstrument,

as for instance by providing a flange 13 adj acent the outer edge of the mouthpiece, the movementof the valves to open position may be conveniently effected by drawing the body outwardly of the mouthpiece after the'latter has been gripped by the teeth, thus rendering the operations of placing the instrument in the mouth of the personand sounding the instrument practically simultaneous. The slot and pin connection between thebody 1 andthe sleeve Gmay be utilized to limit the outward movement of the mouthpiece relak tive to the body so as'to prevent completere-I moval of the mouthpiece fromthe body, and so as to determine the position of the mouth piece on the body, when the vents and mouth of the whistle are open, f V I V 'In the form illustratedin Figs; 5, 6 and 7, the mouthpiece is one with the sleeveas in the form above referred to. 1 In this instance,

however, the sleeve 14 extends farther down on the body 15and is provided with open- 9 ingsor vents16 which register with the vent openings 17 in the body 14 at thatposition of the sleeve relative to the, body whenthe instrument is in condition to be sounded. In this form portions ofthe sleeve below the openings 16 serve as valves to cover the openings 17 as will be understood. Also .in'this] form the stem18 ofthe mouth protecting valve 19 is of such length asto position the latter valve outside of'the whistle casing when the mouth of. the whistle is open. As J illustrated, the stem 18 is of substantial cylindrical structure surmounted by the valve 19 which latter is shouldered and is of size to fit, nicely within the mouth opening in the mouthpiece, the mouth opening being interiorly shouldered to fit the inner face of the valve 19. If desired, and as illustrated,

the sleeve 14 may be continued longitudinally or" the bodyv 15 so as to, completely intions' the bottom 20 ofthe whistle. bodyjwill.

case the'body'whenthe instrument 'is closed withthefvalves covered; Undersuch condi be flush with thelower edge ofthe sleeve 14 and the whistle may be convenientlyplaced in operative condition by applying pressure to said bottom while holding the sleeve. To

body and the sleeve, a recess 21 in the body may beengaged by projections 22 punched inthe metal of thesleeve. -When the whis limit the opening movement between the i he is cylindricah'this device prevents rota-j q i tion of the sleeve on the body as. do'thepin and slotin the other form.v As a convenient way of fastening the valvel19 tothe body, the stem 18 may pass through the plate 3, and its lower portion forked, straddling the partition 2, and fixed thereto.

Thus by the above described construction are accomplished, among others, the objects hereinbefore referred to, and there is produced .a strong, compact whistle of simple construction, which will give the characteristic signal of the police, which will always be ready for immediate operation, andwhich nevertheless, when not in operation, is effectively protected as hereinbefore mentioned.

As many changes could be made in the above construction and many apparently widely difi'erent embodiments of this invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is 1. A whistle comprising, in combination, a hollow body portion having a vent opening in its side wall, a valve slidably mounted on the body portion to cover and uncover said vent opening, a mouth piece movable with said valve and having a mouth opening, an air director fixed relative to said vent opening, and a valve adapted to open and close said mouth opening by movement of said mouth piece, said last mentioned valve being fixed to said body portion and disposed outside the whistle when the mouth opening is open.

2. A whistle including, in combination, a hollow body portion having a partition dividing the interior thereof into unequal compartments, a vent opening in each compartment and an air director fixed relatively thereto, a mouth piece movably mounted on said body portion and having a mouth opening therein, and means for closing said vent openings and said mouth plece opening operated by relative movement of said mouth piece and said body portion.

3. A whistle including, in combination, a hollow body portion having a partition dividing the interior thereof into compartments, a vent opening in each compartment and an air director fixed relatively thereto, a mouth piece movably mounted on said body portion and having an opening therein, a closure for said vent opening operatively associated with said mouth piece, and a valve mounted on said body portion and movable to close said mouth piece opening upon relative movement of said mouth piece and said body portion.

4. A whistle including, in combination, a hollow body portion having a partition dividing the interior thereof into compart ments, a vent opening in each compartment and an air director secured to said partition in fixed relation to said vent opening, a mouth piece movably mounted on said body portion and having an opening therein, a closure for said vent opening operatively associated with said mouth piece, and a valve mounted on said body portion and movable to, close said mouth piece opening upon relative movement of said mouth piece and said body portion. 5.
